a measure derived from the domain of time; the frequency and bispectral analysis of the encephalogram that correlates with depth of sedation and anesthesia in clinical medicine.

bispectral index

A measure of the depth of anaesthesia, which is used to titrate the dose of anaesthetic to prevent unintentional regain of consciousness, especially in patients receiving muscle relaxants to prevent movement, who may not provide visual cues indicating pain.

bispectral index

Abbreviation: BIS
An electroencephalographic measure of the effect of sedative and hypnotic drugs on an anesthetized patient. It is used (along with clinical assessment of the patient) to determine the level of central nervous system depression. The index ranges from zero (completely unresponsive to stimulation) to 100 (awake and alert). At levels below 60, most patients are adequately sedated for surgery.
